4.5 Working fluid
The valve is designed for common hydraulic working fluids:
› mineral oils of performance classes HM and HV according to ISO 6734-4
› non-flammable and difficult to ignite hydraulic fluids according to ISO 12922
› environmentally acceptable hydraulic fluids according to ISO 15380
NOTICE:
NBR seal material is not suitable for some working fluid groups, such as the HFD group.
In case of uncertainty, we recommend to perform a test of the mutual tolerance of the seal material and the working fluid.
